Description:

The Trailertri 18, introduced in 1976 as a revolutionary multihull for home-building, kicked off the era of high performance folding trimarans that have become dominant in races, and highly popular for cruising. The early Trailertri designs had hard chine hulls built in marine sheet ply on plywood frames and stringers. Later more efficient construction methods were adopted.

A development for this model was the Trailertri 680.
